Innovative and environmentally friendly packaging solution: application case of water-soluble film liquid emulsion packaging

Innovative and environmentally friendly packaging solution: application case of water-soluble film liquid emulsion packaging

Project Background

**Industry pain points**

Traditional liquid emulsion products are often packaged in plastic bottles/aluminum foil bags, which have the problems of difficult degradation and high recycling costs. A certain international agrochemical brand is seeking biodegradable and environmentally friendly alternatives to solve the problem of packaging pollution.

Solution

Application of water-soluble film packaging technology

• Material Characteristics: Made of PVOH water-soluble film, stable at room temperature, completely dissolved in water within 30 seconds (adjustable according to actual data)
• Packaging Structure: Three layer composite film design (outer waterproof/middle oxygen barrier/inner water-soluble)
• Filling process: Fully automatic sterile filling line, precise control of single package capacity ± 0.5ml
• Dissolution test: Tested according to ISO 3175 standard with no residue

Technical highlights

✔️  Accurate measurement: Each piece is individually packaged to avoid waste

✔️  Homework safety: Directly put into water for use, reducing the risk of skin contact

✔️  Biodegradation: Natural degradation rate ≥ 90% after 28 days (attached screenshot of test report)

✔️  Transportation protection: Passed ISTA 3A transportation test, no leakage after falling

Customer revenue

• Environmental benefits: Annual reduction of plastic usage by 37 tons
• Cost of use: Comprehensive packaging cost reduced by 22% (compared to traditional solutions)
• Brand Value Added: Obtained EcoVadis Sustainable Development Gold Certification

Application scenarios

◼ Agricultural crop protection: portable pesticide small packaging

◼ Industrial cleaning: Estimated quantity of cleaning agent package

◼ Home care: Concentrated laundry detergent tablets
